安装 RVM
通常使用 RVM 或 rbenv 来安装 Ruby,这里选用 RVM。
$ curl -sSL https://get.rvm.io | bash -s stable
载入 RVM :
$ source /home/libuchao/.rvm/scripts/rvm
$ rvm -v
rvm 1.25.12 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com> ......
再执行以下命令:
$ type rvm
rvm is a function
......
说明 RVM 安装正确。
安装 Ruby
用 RVM 安装 Ruby
$ rvm install 2.1.0
$ rvm use 2.1.0 --default
$ ruby -v
ruby 2.1.0p0
国内服务器推荐替换 RubyGems 的到淘宝镜像
$ gem sources -r https://rubygems.org/
$ gem sources -a http://ruby.taobao.org/
否则安装 Gem 可能会非常非常慢。
安装 Rails
其实 Rails 也是一个 Gem
$ gem install rails --no-ri --no-rdoc -V
......
$ rails -v
Rails 4.0.2
至此,Rails 环境已经安装完成。
安装 MySQL
安装 Mysql 及相应的库文件:
$ sudo apt-get install mysql-server libmysqlclient-dev
然后进行一些安装方面的设置:
$ /usr/bin/mysql_secure_installation
创建相应的数据库,并为它新建一个权限小一些的用户:
mysql> CREATE DATABASE blix_production;
mysql> GRANT ALL PRIVILEGES ON blix_production.* TO blix@localhost IDENTIFIED BY "123456";
mysql> flush privileges;
mysql> exit
导入数据:
$ mysql -u blix -p blix_production < database.sql
安装 Nginx
Nginx 专门处理静态请求,并作为 Unicorn 的反向代理
编辑 /etc/apt/sources.list,末尾处添加以下两行
deb http://nginx.org/packages/ubuntu/ precise nginx
deb-src http://nginx.org/packages/ubuntu/ precise nginx
添加 Nginx 签名
$ wget http://nginx.org/keys/nginx_signing.key
$ sudo apt-key add nginx_signing.key
安装 Nginx
$ sudo apt-get update
$ sudo apt-get install nginx
安装完成后可以在浏览器中输入 http://server-ipaddress 查看是否安装正确。
配置 Unicorn
首先编译一下静态文件:
$ RAILS_ENV=production rake assets:clean
$ RAILS_ENV=production rake assets:precompile
Unicorn 配置参考:
worker_processes 2
timeout 30
APP_PATH = File.expand_path("../..", __FILE__)
working_directory APP_PATH
listen 8080, :tcp_nopush => true
listen "/tmp/unicorn.sock", :backlog => 64
stderr_path APP_PATH + "/log/unicorn.stderr.log"
stdout_path APP_PATH + "/log/unicorn.stdout.log"
pid APP_PATH + "/tmp/pids/unicorn.pid"
Unicorn 自启动脚本:
#!/bin/sh
set -e
# Example init script, this can be used with nginx, too,
# since nginx and unicorn accept the same signals
# Feel free to change any of the following variables for your app:
TIMEOUT=${TIMEOUT-60}
APP_ROOT=/home/libuchao/blix
APP_USER=libuchao
PID=$APP_ROOT/tmp/pids/unicorn.pid
CMD="unicorn_rails -D -E production -c $APP_ROOT/config/unicorn.rb"
action="$1"
set -u
old_pid="$PID.oldbin"
cd $APP_ROOT || exit 1
sig () {
test -s "$PID" && kill -$1 `cat $PID`
}
oldsig () {
test -s $old_pid && kill -$1 `cat $old_pid`
}
case $action in
start)
sig 0 && echo >&2 "Already running" && exit 0
su -c "$CMD" - $APP_USER
;;
stop)
sig QUIT && exit 0
echo >&2 "Not running"
;;
force-stop)
sig TERM && exit 0
echo >&2 "Not running"
;;
restart|reload)
sig HUP && echo reloaded OK && exit 0
echo >&2 "Couldn't reload, starting '$CMD' instead"
su -c "$CMD" - $APP_USER
;;
upgrade)
if sig USR2 && sleep 2 && sig 0 && oldsig QUIT
then
n=$TIMEOUT
while test -s $old_pid && test $n -ge 0
do
printf '.' && sleep 1 && n=$(( $n - 1 ))
done
echo
if test $n -lt 0 && test -s $old_pid
then
echo >&2 "$old_pid still exists after $TIMEOUT seconds"
exit 1
fi
exit 0
fi
echo >&2 "Couldn't upgrade, starting '$CMD' instead"
su -c "$CMD" - $APP_USER
;;
reopen-logs)
sig USR1
;;
*)
echo >&2 "Usage: $0 <start|stop|restart|upgrade|force-stop|reopen-logs>"
exit 1
;;
esac
将这个 shell 在/etc/init.d/下做一个软连接,并使其开机自启动:
$ chmod +x /home/libuchao/blix/config/unicorn_init.sh
$ sudo ln -s /home/libuchao/blix/config/unicorn_init.sh /etc/init.d/unicorn
$ sudo update-rc.d unicorn defaults
启动 Unicorn:
$ service unicorn start
在浏览器中输入 http://server_ipaddress:8080 查看效果。
配置 Nginx
Nginx 配置参考:
upstream blix_backend {
server unix:/tmp/unicorn.sock fail_timeout=0;
}
gzip on;
gzip_disable "msie6";
client_max_body_size 150m;
server {
listen 80 default;
return 403;
}
server {
listen 80;
server_name libuchao.com www.libuchao.com;
root /home/libuchao/blix/public;
try_files $uri/index.html $uri.html $uri @httpapp;
location @httpapp {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_buffering on;
proxy_pass http://blix_backend;
}
location ~ ^(/assets) {
access_log off;
expires max;
}
}
此时应该可以通过域名直接访问了。
